OTT@ ZIETZ, OF HAMBURG, GERMANY.

HEEL FOR BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent N o. 460,904, dated October 6, 1891.

Application tiled August 7, 1890. Serial No. 361,260. (No model.) Patented in France July 4,1890, No. 206,810; in England July 7, 1890, No` 10,519, and in Austria-Hungary December 3,1890,No. 30,248 and No. 56,929.

T all wiz/0m t may concern: v

Be it known that l, (')Tfro ZIETZ, a subject of the Emperor of Germany, and residing at Ilambu rg, in the Empire of Germany, have invented certain new and useful Improvements in Heels for Boots or Shoes, (for which Letters Patent were granted in France July 4, 1890, No. 206,810; in vEngland July 7, 1890, No. 10,519, and in Austria-Hungary December 3, 1.890, No. 30,218 and No. 56,929,) of which the following is a specilication.

My invention relates to an improved heel for boots and shoes; and its object is to provide a heel so constructed that the bottom lift, when worn down, may be easily and quickly replaced by a new one without in any way damaging the heel, and thus obviating the necessity of entirely reheeling the boot or shoe. I attain this object by inserting a metallic plate or skeleton frame between the wood, leather, or composite heel and the bottom or covering lift and attaching the latter to the heel with an adhesive, in the manner hereinafter described and illustrated in the accompanyingT drawings, in which-- Figure 1 is aview of the heel,see'n from un- (lerneath, with the bottom lift removed to show the said metallic plate; Fig. lavertical section through the heel; Fig. S, a front elevation with the bottom lift unattached; Fig. 47,21. transverse section showing the bottom lift attached in position, and Fig. 5 the iinished heel seen from underneath.

Sim ilar letters denote similar parts throughout the several views.

The skeleton-frame plate a is made to lit the bottom surface of the heel exactly, and is attached to the same by brads, screws, or in any other convenient and effective manner. The plate is cut to form aframe around the edges of the heel and provided with a cross-piece Z), connecting the breasting side and back of the frame, so that the parts do do of the under surface of the wood, leather, or composite heel remain uncovered. It is advisable to provide the frame a with short spikes c c for piercing the bottom lift and preventing it from getting displaced while the adhesive is drying.

(Z is the bottom lift, having a flat groove in its upper surface at f extending from the heel-breasting nearly to the back rand, and corresponding in its direction to that of the cross-piece b. Itsupper surface is covered with an adhesive-such as leather-size. The lift is applied and removed in the following manner: The adhesive on the lift is softened by being moistened and the latter applied to the heel, when the glue or size will stick to the surfaces a0 ao of the heel, holding the lift firmly in place. Ou being worn down, the old lift may be easily removed by inserting a sort of chisel or screw-driver into the groove f at the heel-breasting and wrenching it off. No damage whatever will be caused to the heel by removing the lift inthis manner, as the tool or instrument used operates against the metallic cross-piece ZJ, and not against the wood, leather, or composite heel.

If a very thin covering-lift beused, the spikes c c maybe dispensed with and the lift held in place while the adhesive dries by a couple of wire brads c cx, driven through it into the heel from underneath. In such cases the cross-piece b is also unnecessar f, as the metallic frame alone forms a sufficient support for the tool on removing the lift.

Having now fully described my invention, what I claim, and desire to secu re by Letters Patent, is-

Aheel having attached to its undersurface a skeleton frame-plate d, having across-piece l) and spikes c c, in combination with a covering-lift d, having a'groove f and provided with an adhesive on its upper surface, in the manner and for the purpose substantially as described and shown.

In testimony that I claim the foregoing' as my invention I have signed my name, in presence of two witnesses, this 5th day of July, 1800.

OTTO ZIETZ.
